WINDOW.

SPECIFICATION forming part of Letters Patent No. 683,588, dated October 1., 1901.

Application iiled May 20,1898. Serial No. 681,206.

(No model.)

To all wiz/om it may concern:

Be it known that I, .I AMES A. BARR, i'esiding at Nebraska City, in the county of Otoe and State of Nebraska, have invented certain useful Improvements in Windows; and I do hereby declare that the following is a full, clear,

and exact description of the invention, suoli' as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to a new and novel improvement in ventilators for windows.

he 'object of my invention is to provide a ventilator which will prevent the frosting of window-panes, my invention being adapted to be used more particularly in connection with Show-windows.

In the accompanying drawings, Figure l shows a broken view of a show-window provided with my improved ventilator. Fig. 2 shows a central sectional view disclosing the arrangements of the various instrumentalities, while Fig. 3 shows a view illustrating the method of positioning the vertical ventilator-border.

My invention embodies, essentially, a scalloped ventilated border, upon which the lower edge of the window-pane rests, in combination with a second vertical ventilator-strip, and a shield provided with a suitable valve, by means of which the ingress and egress of air may be regulated.

In the accompanying drawings, A represents the side portions, and B the sills, ot' an ordinaryshowwindow,within which the plateglass C is positioned, and which plate C rests upon a scalloped ventilator-strip 4, of metal or of any other suitable material, so as to provide a series of Ventilating-openings, as is clearly shown in Figs. 1 and 2. This strip is positioned horizontally, and adjacent thereto and in juxtaposition therewith is a second Ventilating-strip 5, positioned vertically, scalloped and of any suitable size or material, so that the air coming through the scalloped horizontal strip is permitted a ready escape to the inside of thewindow upon C by virtue of this ventilator-strip 5, as will be more 5c.

fully understood in referring to Figs. 2 and 3. These ventilated strips 4 and are two independent pieces.

Show-windows in winter time are very apt to becomefrosted, so that the goods displayed 515 cannot be seen. 'lo provide a means whereby this frosting of the window-panes may be obviated is the aim of my invention.

To support the ventilator-strip, I provide the bottom plate 2, provided with the up- 6o wardly and outwardly extending portion 3, upon which both the horizontal ventilatorstrip and the vertical ventilator-strip rest. Both the horizontal and the vertical ventilater-strips are intended to come upon the in- 6 5 side of the window. Upon the outside I provide a shield '7, as shown in Fig. 2, which 'shield is provided with openings 10, and a sliding valve is operated by means of a button 9, so that the the object of course being to provide equal temperature upon both sides of the plate C, which prevents the condensation of the vapors and consequent frost-ing of the windows.

While I have shown the ventilator-strip so scalloped, it is of course understood that any other shape could be imparted to the strips without departing from the spirit of my invention.

Having thus described my said invention, 8o

what I claim as new, and desire to secure by United States Letters Patent, is

l. The combination with a window-light, of

a horizontal scalloped ventilator-strip, a verv tical scalloped ventilator-strip positioned adjacent to said horizontal strip, and a plate supporting both of said ventilator-strips, as and for the purpose set forth. y

2. The combination withawindow-light, of

a horizontal scalloped ventilatonstrip, sup- 9o porting said window, a vertical scalloped ventilator-strip, positioned adjacent to said horizontal strip, a base-plate to support both otv said ventilator-strips, and a shield, covering' said horizontal ventilatorstrip, with suitable valved escape-ways, as and for the purpose set forth. Y

3. In a window-ventilator of the character li Y' draft may be regulated, 7o

provided 9 5 described, the combination with a base-plate provided with a Vertical extension, of a horizonta1ventiiator-strip upon said plate and supporting the Window-light., a vertical ventilator-strp positioned between said Windowlght and horizontal Ventilator-strip upon one side, and said v`Vertical extension upon the other side, and a shield to cover said horizontal Ventiiator-strip upon the side opposite said Vertical extension.

In testimony whereof I aiiix my signature in presence of two Witnesses.
